When I plot y=x^2 as...
f[x_] := x^2
Plot[f[x], {x, 0, 2}]
RevolutionPlot3D[{f[x]}, {x, 0, 2}, AxesLabel -> {x, z, y}]
... I get the function rotated about the y-axis (i.e., a parabola).
But what If I want to rotate the function about the x-axis so I get a
funnel-shaped graphic?
Is there an easy way to do this?
I can plot the function in terms of y (x=y^1/2) and get the funnel
but it would easier to just specify the axis of rotation.
Can this be done?
